BEYAZIT TOWER
Beyazit Tower is located in the garden of Istanbul University
and was used as a watch tower of sighting the outbreak
of fires.
Built of wood in 1749, it was damaged, paradoxically,
by fire and then torn down. It was rebuilt in 1878 by the
edict of Sultan Mahmud II. The architect was Senekerim
Balyan.
The 85 meter tower has a roof made of stone and a wooden
staircase. It is still used as a watchtower today as well
as for gathering meteorological data.
CEMBERLITAS BANDED COLUMN
Located on the Divanyolu in the district to which it has
given its name, Çemberlitas, this column was brought
to Istanbul from the Temple of Apollo by Constantinus I
(B.C. 324-327). The column was topped by a statue of Apollo
and, according to pagan tradition, he clasped a javelin
in one hand and a cross in the other. The statue was struck
by lighting and destroyed, later replaced by a marble cross.
The cross was removed during the Ottoman period but the
column was left untouched. Sultan Mustafa II re-enforced
the column with iron bands and built the pedestal on which
it still stands today.
The 35 meter high column is thought to contain relics
belonging to Jesus Christ.

victories of the Pharaoh on its four sides. The western
face of the pedestal contains a representation of Theodosius
I seated on this throne, his wife and children at his side,
receiving ambassadors.

architect Sarkis Balyan in the Neo-baroque and Ottoman
styles.
It is a 27 meter high four-storey structure on two sides

GALATA TOWER
The Galata Tower is found on a hilltop overlooking the
Golden Horn, the Bosphorus and the Sea of Marmara. It was
built by the Genoese in 1348 as the chief tower in the
city walls of Galata. After suffering heavy damage in a
great earthquake in 1509, the tower was repaired by Architect
Hayreddin. The tower is therefore Turkish-made from 13
meters up.Also used as a dungeon, the tower was mostly
used as a look out place to spot the outbreak of fires.
The city was continuously surveyed and upon the sighting
of a fire the public were warned by the beating of a large
drum. The 62 meter-high tower (65.9 with the flag-staff)
is now a popular tourist attraction, with facilities including
a restaurant on the top floor. The balcony ringing the
top floor affords a panoramic view of Istanbul and is an
ideal place to observe the city.
Hazerfan Ahmed Celebi
Hazerfen Ahmed Celebi was a most interesting character
living in Istanbul in the seventeenth century.
He succeeded in flying in a contraption he invented himself.
His first tests took place in Okmeydani (A historical Istanbul
Square where archery practices held) Later he managed to
fly unsethed from Galata tower to Uskudar in his amazing
rocket propelled contraption. He was rewarded by Sultan
Murad IV who watched the flight from Saray Burnu just below
the Topkapi Palace.
The only source of information on Hazerfan Ahmed Celebi
is in the writings of Evliya Celebi who wrote that although
the Sultan rewarded this feat, he considered the ability
to fly a danger and had the aviator exiled to Algeria where
he later died.
GOTLAR COLUMN
The Gotlar Column is found in Gulhane Park and is thought
to have been built in the 4th century. It was erected after
a military victory over the Goths.

pedestal. The column is carved from a single piece of stone
and decorated only by a corinth containing an eagle relief.
KIZ KULESI (MAIDEN'S TOWER)
Built on a small rocky island in the middle of the sea
near Uskudar, where the Marmara Sea meets the Bosphorus,
the Kiz Kulesi (Maiden's Tower, also called Leander's Tower)
has been used for a variety of purposes since its first
construction. First, this small island was used to control
the navy traffic and as a custom's office in 411 B.C..
In the 12th century, the Byzantines used it to project
the Bosphorus and they built a defence tower on the island.
Although the Ottoman Empire continued to use it for the
same reason after the conquest of Istanbul, Sultan Mehmed,
the Conqueror replaced the old tower with a new one.
During the golden years of the Ottoman Empire, the tower
was used as a lighthouse, and, on special occasions, was
used to salute the guests of the Sultans with gun shots.
The tower was completely destroyed by a fire in 1716.
The Prime Minister Nevsehirli Damat Ibrahim Pasha built
today's tower in 1725-25, through in 1943 its wooden walls
were replaced by concrete.
With its white color and its sliced Baroque dome with
a flagstaff on top of the dome, it's a very striking spectacle.
It has become a symbol of Istanbul, and is one of the
first things which comes to one's mind about this city
and has been the subject of many paintings and pictures.
It has recently been renovated and will soon be opened
for sightseeing.
